I've also checked

问题 after having added a command to the Toolbar using addCommandToRightBar(Command), I want to remove or hide the command again (e.g. when I select/unselect on a specific tab in Tabs). In the SideMenuBar there is removeCommand(Command) for this, but I can't figure out how to do the same for Toolbar. Any suggestions how I can achieve this? Thanks 回答1: removeCommand works but you should remember to revalidate() : Toolbar.setGlobalToolbar(true); Form hi = new Form("Bar"); Command cmd = hi.getToolbar
